units: add Wants=initrd-cleanup.service to initrd-switch-root.target (#4345)

`systemctl isolate initrd-switch-root.target` called by initrd-cleanup.service
kills initrd-cleanup.service itself. Then, initrd-cleanup.service failed and
system goes to emergency shell.
To prevent this problem, this commit adds `Wants=initrd-cleanup.service` to
initrd-switch-root.target.

fixes: #4343.
